Hi Bernd,
I appreciate your getting back to me so quickly. Does
anyone else know for sure whether locking and client-side
caching can be disabled on a per file basis?
Many thanks!

Hello,
I am new to this group and I apologize if these issues have
already been addressed. I am somewhat confused about what is
or is not supported in terms of locking, and any help would
be greatly appreciated!
1) Is fcntl currently supported?
Yes, it works, but see e.g. here
https://bugzilla.lustre.org/show_bug.cgi?id=12542
https://bugzilla.lustre.org/show_bug.cgi?id=12802
2) Can locking be disabled on a per file basis?
I don't think so.
3) Can client-side caching be disabled on a per file basis?
I don't think so.
4) Is O_DIRECT supported at the application level?
Works for me.
Cheers,
Bernd
